Main observations

The biogeochemical exchanges based on silvicultural treatments 

Examples of questions asked

What are the effects of the different treatments on the environment? 
What are the forest-soil-atmosphere exchanges?
What are their impacts on tree growth and production?

The long-term biophysical and biogeochemical monitoring device has 3 plots of 9 hectares, representing three contrasting silvicultural treatments monitored for 20 years by a set of automated measuring systems deployed in situ.

It includes:

  • Biophysical and biogeochemical measurements (radiation balance, flow of energy and greenhouse gas emissions, water balance, structure and directional spectral reflectance of vegetation).
  • Monitoring the concentrations and stocks of important elements (N, P, Ca, Mg) in solid and liquid phases of soil and vegetation. 

This monitoring is part of the « Ecosystem « networks of the ICOS and ANAEE European infrastructures.
